(This is a private university in the Shijuku area of central Tokyo. It was the first private engineering school to be established in Japan) Pre-conference tutorials were held on June 22, 1992. The Conference was organized to emphasize visual computing, integrating computer graphics with computer vision. More than 150 scientists attended the week-long conference. In addition to papers there was also an exhibition, industrial seminars, and visits to university and industrial labs. The Proceedings of CGI'92 have been published as follows. Tosiyasu L.
